Letters Patent No. 73,693, dated Januarj28, 1868.

IMPROVEMENT -IN MACHINE FOB. MOULDING PAPER GOILLABS.

TO ALL WHOM' IT MAY CONCERN:

Be it known that we, Gnonon W; CILLEY and Gnoncn H. S'rnunnme, both of Norwich, in the county of New London, and State of Connecticut, have invented a new and improved Mode of Moulding Collars; and we do herebydcclare that the followingis a full, clear, andexact description of the same, reference being had to the accompanying drawings, making a portion of' this specification, in which- Figure 1 is a plan or top view of the apparatus employed in moulding and shaping collars according to our invention.

Figure 2 is a side view of the same.

Figure 3 is a vertical transverse section of the same, taken in the lino x a: of Jig. 2.

Figure 4 is a detached view of one portion of the same.

Similar letters of reference indicate correspondingparts-in all the figures.

This invention relates more especially to the manufacture of paper collars, and it consists in moulding or shaping the collars between two flexible clamping-plates or holders,'which clamp that portion of the collarwhich it is desired to mould,'in such manner as to efi'ectual'ly shape such portion into the form required in the fine ished collar. I

The invention further consists in two flexible 'clampingplatcsz or formers, in combination with suitable means for operating the same, whereby the collar, or such portion thereof as may be desirable, may be clamped between the said plates, and be madeto assume the-desired shape or configuration.

The invention further consists in a novel'combination of parts, whereby not only may the moulding apparatus be very conveniently manipulated when in use, but may, when desired, be securely attached to any suitable support.

To enable others to understand the construction and operation of our invention, we will proceed to describe it with reference to the drawings. I l

The two clamping-plates or formers A. and B are made preferably of sheet steel, and are of any suitable width and length, and, when desired, may be slotted vertically at their upper edges, as shown at a, in figs. 1 and 2, in order to give some degree of vertical elasticity to theplates orformer's. Thesc twoclamping plittes, at .the-centralportion of their upper edges, are curved over, as shown more clearly at b, in figs. 1 and 3, in such manner and form that the transverse section of such portion'of each plate will correspond'to the transverse curvature of the back part. of the finished collar, to whichthe said curved orbent-over portions of the plates are designed to give form and shape, as hereinafter presently set-forth. That surface of the inner plate, A, toward the plate B, has attached to it a layer or thickness, c, of India rubber or equivalent elastic material, and, attached to the outermost side of this plate A, atcach end thereof, is a vertical strap, cl, of a'hinge, the pivot e of which is shown in dotted lines in'fig. 2, a nd the other strap,f, of which turns upon the, said pivot, and is brought upward upon the opposite or outer side of the other plate,.B, as shown in fig. 1. Passing through slots formed in the two straps of each hinge, and 'in the ends of the plates A B, situated between the said straps, is a bar, g, in one end of which is fixed a transverse pin, a, which prevents it from being drawn out of its place;

and, in the opposite end of such bar, is pivoted a cam or eccentric, h, which is furnished with a handle, i, in. such manner that, when theisaid handles'are turned-outward into the position shown in fig. I, the ends of the plates A B will be tightly held or compressedbetween the two hingefstraps df. Formed upon one of the plates A B, one at each end thereof, are two springs, m, which tend to press apart the said plates, when relieved from the action oi. the cams or eccentrics k, as presently herein explained. Secured centrally upon the outer side of the plate A is a strong supporting-piece, n, whi ch, being attached, by screws or otherwise, to a bench or table, holds the apparatus in proper positionwhen in use.

In the operation of moulding or shaping the collars, the handles 2' are first turned inward toward each other, so as to relieve the hinge-.strapffrom the action of the cams or eccentrics h, and thus enable the springs mto force the plates A B apart to a sufficient extent to permit the'insertion between them of the inner fold of the collar, with thc outer fold of such collar, in contact with the outer snrface cfilthe plate 3, as shown in red outlineiu 3, whioh being done, the handles 2' areturned outward into the position shown in fig. 1,-and thus compress together the ends of the plates A B,.as herein before explained. l The ends of the plates or formers A B are then, by means-of the handles t','bent inward,-'as'indicated 'by the arrows in fig. 1, until the'said plates assume the form o t" anare of a-eirfcle, and, inasmuch as the inner plate'A bends upon a smaller are or circle than the other or outer plate 13, it follows that tbe'sai d plates, when thus .bent, are forced toward each other with the greatest forceat their central part's or, in other words,at the curved-or bentover parts b thereof, and, consequently, that portion ofthe eollar'situate'd between such parts, 6, will,be clamped fvith great tightness, and, consequently, moulded or pressed into a shape corresponding to the aforesaid parts 6, such pressure at the same time preventing any stretching or distortion-of the portion thus moulded or shaped, and the end portionsof the collar being permitted to adapt themseli es to the altered shape of the bac k or moulded portion (just described) thereof, by slipping slightly between the plates A B, such slipping being permitted by the comparatively moderate degree of pressureeirerted upon such end portions of: the collar, by the end portions between which they are clamped of the plates or formers} 3 The operation of moulding or shaping the collar being thus completed, theplatesA B are brought back toy or allowed toresuine their straight position, and the handles z'being moved inward, as hereinbefore explained,

the springslm move the plates or formers apart, andperinit the removal of the moulded collar, and the insertion of another, which is then subjected to the"mouldingloperation, in the same manner asherei'nb efore set forth.

Instead of being made ofsb'eet metal, as hereinbfore described, the clamping-plates or formers may be made of any other suitable material, and of any construction nihioh will secure their flexibilityin the moulding v or shaping operation- What we claim as our invention, and desire to se eure by lhetters Patent, is- I 1. The twov flexible clamping-plates or formers A' B, in combination with eccentrics hand handles 1', for

closing and bending the same, substantiaUyasand forithe' purpose specified.

2. The earns or eccentrics h, handles 2', hinge-straps'fi and bars 9, in combination with the clamping-plates ,A-B, springs m, and supporting-piece n, substantially as and for the purpose specified.
